Instead of feeding aggressively through the afternoon hours and well into the evening, they are spending a half hour or so in the corn and more time munching woody browse. They are lying up all night in the thickest densest thermal cover they can find and spending most of their daylight hours bedded on south-facing slopes--you can't cut a track on a north-facing slope. You see where they have ambled along, nipping a bud here and a shoot there. Maybe they pawed through the snow to find an errant acorn or something green. Instead of walking a half mile to feed on standing corn, they will walk 20 yards to chew on some woody browse or nip off the last vestiges of something that grew last summer.
